Anti-corrosion tough anti-gas-channeling cement paste as well as preparation and application thereof
The invention relates to anti-corrosion tough anti-gas-channeling cement paste which comprises the following components in parts by mass: 100 parts of API G-grade oil well cement, 10-30 parts of silicon powder, 5-30 parts of an anti-corrosion agent, 10-25 parts of a toughening agent, 1.5-4 parts of an anti-gas-channeling agent, 1-5 parts of a fluid loss agent, 0.5-2 parts of a dispersing agent, 0-1.5 parts of a retarder, 0.05-0.3 part of a defoaming agent and 38-120 parts of water. The invention also relates to the preparation and application thereof. The water loss of the cement slurry API for well cementation is controllable, the thickening time is adjustable, a cementing material can be generated when the cement slurry API for well cementation is used through research, the strength of the cement slurry does not decline at the temperature of 120 DEG C, and meanwhile the cementing material cannot be corroded by CO2.
本发明涉及一种防腐蚀韧性防气窜水泥浆，含有如下质量份数的组分：API G级油井水泥100份，硅粉10～30份，抗腐蚀剂5～30份，增韧剂10～25份，防气窜剂1.5～4份，降失水剂1～5份，分散剂0.5～2份，缓凝剂0～1.5份，消泡剂0.05～0.3份，38～120份的水。本发明还涉及其制备和应用。本发明提供的固井用水泥浆API失水量可控，稠化时间可调，经研究，其在使用时会生成为一种胶凝材料，能够在120℃温度条件下强度不衰退，同时该胶凝材料不会被CO2腐蚀。
